[0031] The embodiments of the present invention are described in detail below, and the examples of the embodiments are shown in the accompanying drawings. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention. Those of ordinary skill in the art can make various changes, modifications, substitutions, and variations to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the claims and their equivalents.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. Additionally, the terms "comprising", "including" and any variations thereof are intended to cover non-exclusive inclusion.

[0033] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installed" and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] Currently, many automobiles are equipped with a PEPS (also known as Comfort Access or Keyless Entry) system. When a driver carrying the original vehicle remote control steps into the designated range, the door will automatically unlock when the driver pulls the door handle, and the door will automatically lock when the driver presses a designated position on the door handle. Due to the limited number of original vehicle remote controls, when multiple people share the same vehicle, they need to reserve in advance and obtain the original vehicle remote control, which is not convenient in actual use.

[0035] To overcome or at least partially solve the above problems, the embodiments of the present application provide a device for unlocking and locking the original vehicle door handle using the original vehicle remote control inside the vehicle. Through this device, the driver can unlock and lock the door without carrying the original vehicle remote control. The following will be described in detail through embodiments.

[0036] Figure 1 This is the working principle diagram of the device for unlocking and locking the original vehicle door handle using the original vehicle remote control inside the vehicle provided in Embodiment 1 of the present invention. The device for unlocking and locking the original vehicle door handle using the original vehicle remote control inside the vehicle includes an original vehicle remote control, a control box, and a smart remote control.

[0037] The original vehicle remote control, that is, the original vehicle smart key, is arranged inside the vehicle. It can communicate with the devices inside the vehicle by receiving a first radio signal to enable the vehicle to determine whether the original vehicle remote control is inside the vehicle, and can communicate with the devices inside the vehicle by sending a second radio signal to transmit a control command for unlocking and locking the door to the vehicle.

[0038] When the driver carrying the original vehicle remote control steps into the specified range, such as within 1 meter of the vehicle, and the driver pulls the door handle, after the vehicle receives the unlocking action signal, it sends the unlocking action signal to the vehicle's low-frequency antenna. After the vehicle's low-frequency antenna receives the unlocking action signal, it sends a first radio signal - a low-frequency trigger signal to the original vehicle remote control. After the original vehicle remote control receives the low-frequency trigger signal, it sends a second radio signal - a high-frequency unlocking signal. After the vehicle's high-frequency receiver receives the high-frequency unlocking signal, the door unlocks. It should be understood that the first radio signal and the second radio signal can also be other radio signals, which are not listed one by one here.

[0039] Generally, when the original vehicle remote control is arranged inside the vehicle, the devices inside the vehicle can confirm that the original vehicle remote control is inside the vehicle by communicating with the original vehicle remote control, so that the operation of locking the vehicle cannot be realized outside the vehicle. In this embodiment, a control box arranged inside the vehicle is used to prevent or interfere with the original vehicle remote control from communicating with the devices inside the vehicle by receiving the first radio signal, so that the vehicle cannot judge the position of the original vehicle remote control. Thus, even if the original vehicle remote control is arranged inside the vehicle, it does not affect the operation of locking the vehicle outside the vehicle.

[0040] The control box is communicatively connected to the devices inside the vehicle and can obtain the original vehicle door handle lock / unlock action signal from the devices inside the vehicle. For example, the control box may include a decoder and a central processor, and the decoder is communicatively connected to the central processor; the decoder can be connected to the devices inside the vehicle (such as the original vehicle door handle lock / unlock action sensing device) through a Lin line, and the decoder can be a Lin line decoder. The devices inside the vehicle send the original vehicle door handle lock / unlock action signal to the decoder through the Lin line, and then the decoder decodes it and sends it to the central processor.

[0041] The decoder may also include a CAN bus decoder and a Lin line decoder. The CAN bus decoder obtains the original vehicle door handle lock / unlock action signal of the devices inside the vehicle (such as the original vehicle door handle lock / unlock action sensing device) through the CAN bus, decodes it and sends it to the Lin line decoder through the Lin line, and then the Lin line decoder decodes it and sends it to the central processor.

[0042] The intelligent remote control can communicate with the control box by receiving a third radio signal so that the control box can judge whether the intelligent remote control is inside the vehicle, and can communicate with the control box by sending a fourth radio signal to transmit the control command for locking / unlocking the vehicle door to the control box. After the control box judges that the intelligent remote control is outside the vehicle, obtains the original vehicle door handle lock / unlock action signal, and receives the control command for locking / unlocking the vehicle door transmitted by the intelligent remote control, it prevents or interferes with the original vehicle remote control from communicating with the devices inside the vehicle by receiving the first radio signal, and controls the original vehicle remote control to transmit the control command for locking / unlocking the vehicle door to the vehicle.

[0043] For example, when a driver carrying a smart remote control steps into a specified range, such as within 1 meter of the vehicle, the control box sends a third radio signal, such as an RFID 125KHZ low-frequency signal, to the smart remote control. After receiving the third radio signal, the smart remote control sends a fourth radio signal, such as an FSK 394MHZ high-frequency signal. After receiving the fourth radio signal, the control box blocks or interferes with the original vehicle remote control from communicating with the devices inside the vehicle by receiving the first radio signal, making the vehicle unable to determine the position of the original vehicle remote control. If a signal indicating the action of locking or unlocking the original vehicle's door handle is obtained, the control box controls the original vehicle remote control to send a control command for locking or unlocking the vehicle door to the vehicle, such as controlling the original vehicle remote control to send a second radio signal to the vehicle's high-frequency receiver. After receiving the second radio signal, the vehicle's high-frequency receiver performs the action of locking or unlocking the vehicle door.

[0044] Specifically, the control box may include a signal receiving module, a signal sending module, a central processor, and a controller. The central processor is communicatively connected to the signal receiving module, the signal sending module, and the controller respectively. The signal receiving module is capable of receiving the fourth radio signal, and the signal sending module is capable of sending the third radio signal. The controller is capable of sending a control instruction to the original vehicle remote control, and the original vehicle remote control sends a control command for locking or unlocking the vehicle door to the vehicle according to this control instruction.

[0045] In one implementation, the original vehicle remote control includes a first radio signal receiving antenna. The control box may further include an analog circuit, which is communicatively connected to the controller and is used to short-circuit the first radio signal receiving antenna, that is, to make the original vehicle remote control unable to send the first radio signal, thereby preventing the original vehicle remote control from communicating with the devices inside the vehicle by receiving the first radio signal and making the vehicle unable to determine the position of the original vehicle remote control.

[0046] In another implementation, the control box may further include an interference module, which is communicatively connected to the controller and is used to generate a radio signal with the same frequency as the first radio signal to interfere with the original vehicle remote control from communicating with the devices inside the vehicle by receiving the first radio signal and making the vehicle unable to determine the position of the original vehicle remote control.

[0047] The interference module may include a single-chip microcomputer, an amplifier circuit, and a transmitting antenna, which are electrically connected in sequence.

[0048] In yet another implementation, the control box may further include an execution circuit, which is communicatively connected to the controller and is used to open the circuit of the first radio signal transmitting antenna of the vehicle to prevent the original vehicle remote control from communicating with the devices inside the vehicle by receiving the first radio signal and making the vehicle unable to determine the position of the original vehicle remote control.

[0049] In this embodiment, a control box is used to block or interfere with the original vehicle remote control from communicating with the devices inside the vehicle by receiving the first radio signal, so that the vehicle cannot determine the position of the original vehicle remote control. Thus, even if the original vehicle remote control is arranged inside the vehicle, it does not affect the operation of locking the vehicle outside the vehicle. After the control box determines that the intelligent remote control is outside the vehicle, obtains the original vehicle door handle lock / unlock action signal, and receives the control command for locking / unlocking the vehicle door transmitted by the intelligent remote control, it blocks or interferes with the original vehicle remote control from communicating with the devices inside the vehicle by receiving the first radio signal, and controls the original vehicle remote control to transmit the control command for locking / unlocking the vehicle door to the vehicle.

[0050] For the situation where multiple drivers share the same vehicle, an intelligent remote control can be configured for each driver, and the driver can use their respective intelligent remote controls to lock and unlock the vehicle door. Thus, it solves the problem that when multiple people share the same vehicle, it is necessary to reserve and obtain the original vehicle remote control in advance, which is not convenient in actual applications.

[0051] Figure 2 This is the working principle diagram of the device for locking and unlocking the original vehicle door handle using the original vehicle remote control inside the vehicle provided in the second embodiment of the present invention. The device for locking and unlocking the original vehicle door handle using the original vehicle remote control inside the vehicle includes an original vehicle remote control, a control box, and an intelligent remote control.

[0052] The original vehicle remote control, that is, the original vehicle intelligent key, is arranged inside the vehicle. It can communicate with the devices inside the vehicle by receiving the first radio signal so that the vehicle can determine whether the original vehicle remote control is inside the vehicle, and can communicate with the devices inside the vehicle by sending the second radio signal to transmit the control command for locking and unlocking the vehicle door to the vehicle.

[0053] The control box is arranged inside the vehicle. It can switch the signal positions of the first transmitting antenna arranged inside the vehicle and the second transmitting antenna arranged outside the vehicle. Both the first transmitting antenna and the second transmitting antenna can send the first radio signal. The control box is communicatively connected to the devices inside the vehicle and can obtain the original vehicle door handle lock / unlock action signal from the devices inside the vehicle.

[0054] The intelligent remote control can communicate with the control box by receiving the third radio signal so that the control box can determine whether the intelligent remote control is inside the vehicle, and can communicate with the control box by sending the fourth radio signal to transmit the control command for locking and unlocking the vehicle door to the control box.

[0055] After the control box determines that the intelligent remote control is outside the vehicle, obtains the original vehicle door handle lock / unlock action signal, and receives the control command for locking and unlocking the vehicle door transmitted by the intelligent remote control, it switches the signal positions of the first transmitting antenna and the second transmitting antenna so that the vehicle determines that the original vehicle remote control is outside the vehicle. After the control box determines that the intelligent remote control is inside the vehicle, it switches the signal positions of the first transmitting antenna and the second transmitting antenna again.

[0056] Before switching the signal positions of both the first transmitting antenna and the second transmitting antenna, when the original vehicle remote control communicates with the equipment inside the vehicle by receiving the first radio signal transmitted by the first transmitting antenna arranged inside the vehicle, the vehicle determines that the original vehicle remote control is inside the vehicle; when the original vehicle remote control communicates with the equipment inside the vehicle by receiving the first radio signal transmitted by the second transmitting antenna arranged outside the vehicle, the vehicle determines that the original vehicle remote control is outside the vehicle.

[0057] After the signal positions of both the first transmitting antenna and the second transmitting antenna are switched for the first time, when the original vehicle remote control communicates with the equipment inside the vehicle by receiving the first radio signal transmitted by the first transmitting antenna arranged inside the vehicle, the vehicle determines that the original vehicle remote control is outside the vehicle; when the original vehicle remote control communicates with the equipment inside the vehicle by receiving the first radio signal transmitted by the second transmitting antenna arranged outside the vehicle, the vehicle determines that the original vehicle remote control is inside the vehicle. Therefore, when the signal positions of both the first transmitting antenna and the second transmitting antenna are switched for the first time, the vehicle will determine that the original vehicle remote control is outside the vehicle, while in actuality the original vehicle remote control is arranged inside the vehicle. In this case, after the vehicle obtains the signal of the original vehicle door handle for locking and unlocking and receives the control command for locking and unlocking the vehicle door sent by the original vehicle remote control, it will perform the action of locking and unlocking the vehicle door. After the control box determines that the intelligent remote control is inside the vehicle, it switches the signal positions of both the first transmitting antenna and the second transmitting antenna again. The original vehicle remote control communicates with the equipment inside the vehicle by receiving the first radio signal transmitted by the first transmitting antenna arranged inside the vehicle, and the vehicle determines that the original vehicle remote control is inside the vehicle, so that the vehicle can be started normally.

[0058] For the situation where multiple drivers share the same vehicle, intelligent remote controls can be configured for each driver, and the drivers can use their respective intelligent remote controls to lock and unlock the vehicle doors. Thus, it solves the problem that when multiple people share the same vehicle, it is necessary to reserve and obtain the original vehicle remote control in advance, which is not convenient in actual applications.

[0059] Specifically, the control box may include a signal receiving module, a signal sending module, a central processing unit, a controller, and two double-pole relays. The central processing unit is respectively communicatively connected to the signal receiving module, the signal sending module, and the controller. The signal receiving module can receive the fourth radio signal, and the signal sending module can send the third radio signal. The controller can control the double-pole relay to perform the action of switching the signal positions of both the first transmitting antenna and the second transmitting antenna.

[0060] Figure 3 This is the working principle diagram of the device for locking and unlocking the original vehicle door handle with the original vehicle remote control inside the vehicle provided in the third embodiment of the present invention. The device for locking and unlocking the original vehicle door handle with the original vehicle remote control inside the vehicle includes an original vehicle remote control, a control box, and an intelligent remote control.

[0061] The original vehicle remote controller is arranged inside the vehicle. It can communicate with the devices inside the vehicle by receiving the first radio signal so that the vehicle can determine whether the original vehicle remote controller is inside the vehicle, and can communicate with the devices inside the vehicle by sending the second radio signal to transmit the control command for locking and unlocking the vehicle doors.

[0062] The control box is arranged inside the vehicle. It can open the circuit of the first transmitting antenna arranged inside the vehicle. Both the first transmitting antenna arranged inside the vehicle and the second transmitting antenna arranged outside the vehicle can send the first radio signal. The control box is communicatively connected to the devices inside the vehicle and can obtain the original vehicle door handle lock / unlock action signal from the devices inside the vehicle.

[0063] The intelligent remote controller can communicate with the control box by receiving the third radio signal so that the control box can determine whether the intelligent remote controller is inside the vehicle, and can communicate with the control box by sending the fourth radio signal to transmit the control command for locking and unlocking the vehicle doors.

[0064] After the control box determines that the intelligent remote controller is outside the vehicle, obtains the original vehicle door handle lock / unlock action signal, and receives the control command for locking and unlocking the vehicle doors transmitted by the intelligent remote controller, it opens the circuit of the first transmitting antenna. The original vehicle remote controller receives the first radio signal sent by the second transmitting antenna so that the vehicle can determine that the original vehicle remote controller is outside the vehicle. In this case, when the vehicle obtains the original vehicle door handle lock / unlock action signal and receives the control command for locking and unlocking the vehicle doors sent by the original vehicle remote controller, it then performs the door lock / unlock action. After the control box determines that the intelligent remote controller is inside the vehicle, it restores the signal transmission of the first transmitting antenna so that the vehicle can determine that the original vehicle remote controller is inside the vehicle, thus enabling the vehicle to start normally.

[0065] For the situation where multiple drivers share the same vehicle, intelligent remote controllers can be configured for each driver, and the drivers can use their respective intelligent remote controllers to lock and unlock the vehicle doors. Thus, it solves the problem that when multiple people share the same vehicle, it is necessary to reserve and obtain the original vehicle remote controller in advance, which is not convenient in actual application.

[0066] Specifically, the control box may include a signal receiving module, a signal sending module, a central processing unit, a controller, and an execution circuit. The central processing unit is communicatively connected to the signal receiving module, the signal sending module, and the controller respectively. The signal receiving module can receive the fourth radio signal, and the signal sending module can send the third radio signal. The controller can control the execution circuit to perform the opening and closing of the circuit of the first transmitting antenna.
